You are so lucky that it was not a deadly snake but did the right thing by going to the hospital. The best thing to do for a snake night is to apply a tight bandage or piece of cloth over the would to minimise the blood flow, I do not think sucking the would works except in the movies! I think you can also apply a bandage above the wound as well to slow blood flow up onto the limb. Usually people’s Adrenalin increases their heart beat and this can also make it worse, hard to control though when you are in a panic state. I know I would be. So glad u are ok 🙏
